A

Answer to Question 2

Study of Mercury's precession reveals that it precesses more slowly than Newtonian gravity would predict. It takes a general relativity-based approach, accounting for the curvature of spacetime, to correctly predict the precession rate. General Relativistic corrections to time have also been tested by synchronizing clocks that then are flown on airplanes and satellites.
